Abstract

The invention provides a data transmission method in MEC and a communication device, and the method comprises the steps: transmitting first information to a network element of a core network, whereinthe first information comprises the identification of a cell where terminal equipment is located and the identification of an initiated first application; receiving first response information sent bythe network element of the core network, wherein the first response information comprises a DNAI corresponding to the cell identifier; sending a service request for requesting service data corresponding to the first application to a core network element, wherein the service request comprises the DNAI; and receiving second response information from the network element of the core network, wherein the second response information comprises an identifier of the MEC platform corresponding to the positions of the DNAI and the terminal equipment and an identifier of a CDN node on the MEC platform. According to the method provided by the invention, the MEC platform needing to be accessed by the user and the CDN edge node on the MEC platform are determined before the user officially initiates the service access, so that user communication failure caused by distribution of the shunting strategy is avoided, interruption of a communication link is avoided, and the user experience is improved.

Description

technical field [0001] The present application relates to the field of communication, and more specifically, to a method and communication device for data transmission in MEC. Background technique [0002] Mobile edge computing (MEC) is a technology based on the evolution architecture of the fifth generation (5rd generation, 5G) system, which deeply integrates the access network and Internet services. It deploys the application server (application server, AS) and mobile broadband (MBB) core network part of the business processing and resource scheduling functions to the edge of the network close to the access network, behind the 5G base station, closer to the user (or terminal equipment) provides a computing environment that supports the deployment of third-party services (such as content delivery network (CDN) edge nodes) on the MEC platform, making services closer to users, providing faster download speeds, lower Access latency. [0003] At present, third-party services ...
